Abstract

The machines of the invention incorporate a new system for extracting the juice, as well a high capacity supply assembly.
The system of the invention comprises two alveoli (9) each of which has an integral arm (10) coupled to rotating and vertically displaceable axes (11). The alveoli trace a semicircular trajectory with the piece of fruit located in one of them, said piece of fruit then being divided into two equal parts by an intermediate blade (14), said alveoli then moving into a lower position in which they each face squeezing cones (17). Once in this position, the alveoli (9) descend vertically and press both halves of the piece of fruit against the squeezing cones, the juice falling into a lower tray (18) and from there into a glass (21) or similar by means of an outlet tube (20). Afterwards, the alveoli repeat the same process in reverse in order to return to their initial position and receive the next piece of fruit.
The supply assembly comprises a revolving divider (1) which incorporates sleeves (2) for containing the pieces of fruit which pass one at a time to one of the alveoli (9).

Description

  • The present invention relates to a number of perfections to machines for squeezing citrus fruits. These machines incorporate a novel, high capacity "revolver" system in which the oranges or other pieces of fruit are placed. They also include an innovative mechanism for squeezing each piece of fruit, the extraction of the juice being carried out by means of a small vertical displacement whereby each half of the piece of fruit located in its respective alveolus presses against the corresponding squeezing cone. Conventionally, the extraction of the juice is carried out by means of a simultaneous and coincident rotating motion of the cones and the corresponding alveoli.
  • By means of the perfections introduced by the present invention it is possible to achieve very clear fruit juices, taking full advantage of the fruit. Furthermore, said fruit juices can be obtained at room temperature or at colder temperatures.
  • Also the machine in question can be cleaned very easily since it can be assembled and disassembled quickly and easily without the need of any tools.
  • Moreover, it provides a high yield.
  • As a precaution, the machine in question comprises a transparent cover which, when it is removed, paralyses the squeezing mechanism.
  • BACKGROUND OF THE INVENTION
  • Currently known orange squeezing machines are based on rotating drums provided with a numberof alveoli which act together with cones which also rotate so as to squeeze the orange halves or other types of fruit which have been previously cut by a central blade.
  • Said squeezing cones rotate by means of a translation movement, the squeezing action being applied gradually to the orange half or other type of fruit.
  • These conventional machines do not take full advantage of the juices which can be obtained from the various types of fruit, and in some cases it is very difficult to gain access to their interiors for cleaning purposes.
  • DESCRIPTION OF THE INVENTION
  • The perfections to machines for squeezing citrus fruits which form the object of the present invention include a number of notable improvements over the conventional machines and at the same time solve to a large extent the problems described above.
  • The squeezing machine of the invention comprises in general a supply assembly controlled by a revolving divider, two alveoli each with integral rotating arms guided by vertical grooves, a blade for cutting the fruit and a number of squeezing cones. With this arrangement, when a piece of fruit from the supply assembly becomes positioned in one of the two alveoli, the rotating arms together with the alveoli turn through 180° until they reach a lower, opposite position in which the two halves of the piece of fruit are squeezed as the corresponding cones press on them by means of the vertical descending motion of the arms. Said piece of fruit is of course cut in two by the blade positioned between the two circular trajectories of the two alveoli whilst they are facing each other, each alveolus receiving an equal part of the piece of fruit which, in the final part of its motion, slides along slip ramps. Afterwards, as the alveoli rise, the peel remains suspended above circular windows in each of said ramps. The ramps rise in unison a certain amount of time after the alveoli, the delay being sufficient for the alveoli to cover at least half of the way to their initial position. In this way when the alveoli rotate into their initial position in order to receive the next piece of fruit and then position themselves once again in front of the circular windows for the squeezing process, the pieces of peel are ejected by the alveoli themselves during the final part of their trajectory.
  • In order that the present invention may be better understood, the accompanying drawings illustrate the object of the invention by way of a non limiting example.
  • BRIEF DESCRIPTION OF THE DRAWINGS
    • Figure 1 shows an elevation view of a machine for squeezing citrus fruits in which a number of perfections have been incorporated according to the object of the invention.
    • Figure 2 shows a similar view to the one described above in which the machine in question is in the position for squeezing fruit.
    • Figure 3 shows a plan view of a slide track forming part of the supply assembly, said track comprising a window through which pieces of fruit fall due to the effect of gravity towards the alveoli.
    DESCRIPTION OF A PREFERRED EMBODIMENT
  • Referring to the figures, the machines for squeezing citrus fruits in which a number of perfections have been incorporated comprise a supply assembly which consists of revolving load divider 1 to sleeves 2 for containing the pieces of fruit are coupled, said pieces of fruit being supported by dispensing suspending cams 3 which, when they come into contact with a stop or cam release 5, can pivot in a horizontal plane. Said cams 3 pivot about a small axis 4 connected to the revolving divider. Underneath is a slide track for the pieces of fruit provided with a supply window 7 and an unloading step 8.
  • The pieces of fruit located in the containing sleeves 2 fall one at a time due to the effect of gravity into one of the two alveoli 9, each of which has an integral rotating arm 10 connected to axes 11 which are guided by vertical grooves 12 in the housing 13 of the machine of the invention. As the revolving divider 1 is rotates by impulses, the corresponding dispensing cam 2 comes into contact with the stop 5 and allows one of the pieces of fruit to pass, said piece of fruit becoming settled on the unloading step 8 and the cam 3 returning to its initial position. The piece of fruit is then moved along to the window 7 through which it falls into one of the alveoli 9.
  • Starting in the uppermost position (figure 1), the alveoli 9 and the arms 10 rotate through 180° until they reach an lower, opposite position (figure 2) following a semicircular trajectory, and in such a way that when said alveoli 9 are facing each other the piece of fruit is cut through the middle by means of an intermediate blade 14, each of the two equal halves locating in the corresponding alveolus, and thereafter travel the remaining 90° of their circular trajectory along slip ramps 15, at the ends of which are cir- cularwindows 16 which face squeezing cones 17. Beneath said cones, and in a corresponding position thereto, is a tray 18 provided with a juice filter sieve 19, said tray comprising a small lower tube 20 through which the juice flows into a glass 21 or similar.
  • With this arrangement, when the alveoli 9 which contain the two halves of the piece of fruit are in the lower position facing the cones 17, and of course the circular windows 16, they descend vertically downwards together with the arms 10 and the axes 11, guided by the grooves 12, in such a way that the two halves of the piece of fruit are thoroughly squeezed by pressing against the cones 17, the juice thereby falling into the tray 18 and from there into the glass 21. The slip ramps 15, as well as the blade 14, are linked to the axes 11 and are guided by a central vertical groove 22 along which they follow the vertical movement of the arms 10, the alveoli 9 and the axes 11.
  • Once the juice has been extracted, the alveoli 9 rise upwards, the pieces of peel of the fruit resting over the circular windows 16. The ramps 15 rise in unison a certain amount of time after the alveoli, the delay being sufficient for the alveoli to cover at least half of the way to their initial position. After the alveoli 9 have risen, the arms 10 are made to rotate in the opposite direction until they reach their initial position where one of the alveoli 9 receives another piece of fruit which falls due to the effect of gravity from one of the containing sleeves 2. The same cycle is then repeated, said pieces of peel trapped over the circular windows being moved and ejected by means of the alveoli 9 themselves which run into said pieces of peel at the end of their trajectory.
  • The machine of the invention, which is provided with a manual or coin-operated cycle selector, can accept pieces of fruit of various sizes. Therefore, the windows 16 situated above the squeezing cones 17 are provided with small flaps which descend and rise, during both the fruit pressing cycle and the cycle in which the rind or peel is lifted for extraction, so that as they move they follow closely the profile or surface of the squeezing cone, thus preventing the fruit and peel from falling even in cases of large differences in size.
  • The cleaning process is easy since all the component parts which come into contact with the juice can be assembled and disassembled in a matter of seconds without the need of tools. Furthermore there are no corners in which the juice might ferment and become contaminated.
